Abstract: 9487. Bundy, W. Le. G. May 5. Date and time printing stamps. - A time-recorder or tell-tale is adapted to be used with a time card, Fig. 8, to be carried by the workman, who inserts it into a holder 100, Fig. 3, and then works a handle 29, when the hour - wheel 1 and the minutewheel 2, Fig. 7, print upon it the time of insertion, which may be the time of leaving or arriving &c. Also, the card being preferably spaced horizontally and vertically, as shown, to denote the morning and afternoon of the several days of the week, and the arrival and departure &c., the apparatus is adapted to be moved horizontally by means of a handle 9, and a holder 11 on which the card rests is automatically moved vertically by means of mechanism connected with clockwork which works the apparatus. The wheels 1 and 2, carrying the hour and minute numerals respectively, are connected by a suitable gearing with the clockwork mechanism. In front of the wheels passes an inking-ribbon 56, which can be wound on and off the rolls 57, 58. On the hand-lever 29 being depressed, the stamp or platen 4, carried at the top of the pivoted lever 30 in front of the inserted card, is first caused to recede from the card, and is then suddenly struck against it by the spring 32, thus stamping it against the time-wheels to print the time. The mechanism connecting the holder 11 with the clock mechanism consists of a rack or ratchet bar which is actuated at the end of every twelve hours to lift the card the height of one of the spaces formed by the horizontal lines, and finally, in the case of the card shown, it is returned to its original position after fourteen such movements. An index 98 connected with the ratchet bar denotes which of the divisions of the card formed by horizontal lines will be printed upon. The printing-wheels &c., which are mounted on a slide 5, are moved horizontally by the hand-lever 9, through rack and pinion gear 73, Fig. 7. The handle is also adapted to serve as an index, as shown in Fig. 1, to denote which of the divisions formed by vertical lines will be printed upon.

Abstract: 8535. Smith, A., Haggas, H., Newsolme, R., and Clough, S., [Executors of Hattersley, R. L.], and Jackson, S. May 9. Loom change - box motions; picking-mechanism.- The pattern cylinder 10, for controlling the picking and box mechanism, is secured to a sleeve 9 which may be mounted upon the shaft 1 of an ordinary dobby. The sleeve carries a star-wheel 8, which is driven by a pin-wheel 6 secured to a countersbaft 4, driven from the shaft 1 by means of toothed gearing 3, 5. A lever 11, actuated by the pattern pegs 21, is connected by a rod 13 to a lever 12 which is pivoted to a cam-actuated lever 15. The lower end of the rod 13 is slotted, and rides upon a pin 22, on the lever 12, which is provided with a pin or projection 19 bearing against the lower end of the rod 13. A rod 16 connects the lever 12 to the picking-mechanism. When the lever 11 is not acted upon by a peg 21, the projection 19 bears against the rod 13, and the levers 12, 15 move as one lever and raise the rod 16, as shown in Fig. 5, but, when a peg acts upon the lever 11, the lever 12 is first raised so as to release the lower end of the rod 13 from engagement with the projection 19, and then the lever 15 is raised by the cam, shown in Fig. 4, thus causing the lever 12 to oscillate about its fulcrum 22, and depress the rod 16. The connections between the pattern cylinder and box motion are of the ordinary kind. The mechanism is applicable to box motions of the kind described in Specification No. 8773, A.D. 1888. The shuttle is picked from either side of the loom, according to the action of the above-described mechanism, and then to and fro a number of times determined by the gear-ratios of the wheels 3, 5, 6, 8.
